HighLight DL-HP SeriesHigh-Power Diode Laser

Coherent HighLight™ DL-HP series products are high-power (3 kW to 8 kW), fiber delivered, industrial diode lasers that offer unmatched convenience and economy for metal processing applications such as large area cladding, heat treating, and brazing. Ease of use in HighLight DL-HP lasers is enhanced because their highly reliable, conduction-cooled diodes do not require deionized cooling water. Additionally, these lasers support plug-and-play fiber exchange by the user, and their web interface enables simplified access and control through any device with a web browser.

A wide range of options and accessories are available for HighLight DL-HP series products to provide flexibility for integration and to facilitate their use in a variety of settings. For example, climate control of the laser enclosure allows operation in high humidity environments.
